Following up to my own post, I found that the previous owners of this
vehicle didn't know what the real problem was, since it wasn't the
transfer case, or at least it was more than just the transfer case.
After I posted the previous message, I found some spare time to put a
battery into the Isuzu and tried ****fting through the transfer cases
gears, when I noticed that when I pressed on the gas a bit when in 4
Hi and 4Lo, it seemed to be trying to move. But when I had it in 2Hi,
I just heard a rubbing noise under the vehicle.
Not wanting to get out and look underneath while the engine was
running and it was in gear, I opted for jacking up the back end and
putting it on blocks, before doing this. When I did, I found that the
drive shaft was turning, (I think maybe the steady bearing might be
going as this seemed to be the source of the rubbing sound), but the
rear tires didn't turn. And with the engine turned off and the
transmission in park, the drivers side rear tire could be spun as if
there wasn't anything connected to it. It started to rain about then,
so I put off further investigation until tomorrow, weather permitting.
I'll be taking the inspection cover off of the rear end and having a
good look at how things mesh, first chance I get, but I'm suspecting
that the axle shaft snapped, (if I'm lucky). I'd rather replace a
broken axle shaft than try to replace the crown and pinion gears, or
the entire rear end.
I'm still interested in parts interchange info if anyone has any for
the drive train on this vehicle. Thanks!
